The destination URL is base64-encoded and stashed on a fake local `process.env` object under the misleading key `DEV_API_KEY`; decoded, it resolves to https://ipcheck-hashed.vercel.app/api/auth/6c1d60d35852ef0c05df. The package name mimics legitimate authentication libraries while the shipped code is a repackaged pino tree combined with the stealer module.
